Subject: [PATCH] cr: don't restore net namespace by default

since runc don't manage net device and their configuration, checkpoint
also don't dump net namespace by default, so set 'nsmask = unix.CLONE_NEWNET'
by default in restore. Or if user do not pass 'empty-ns network', criu will
cost extra time in restore.
